The MARBERO 88.8Wh Portable Power Station is worth buying if you want a small backup for phones, monitors and camp lights. It weighs 2.27 lbs, holds 24,000mAh, and charged my phone and the baby monitor at the same time. Buy. Skip it if you need to run appliances.

How this review was made: written from my own video review of this product. Every opinion here is my own, from using it myself.
Quick Verdict
It rains constantly where I live and the power goes out constantly with it, so I needed something that wouldn’t take up much space but was still powerful. This one is 2.27 lbs, charged my phone and the baby monitor at the same time, and lives in a drawer between outages. For power outages with phones, monitors, and lights, and nothing else, this works.
Buy if you:
- lose power often and just need phones, monitors and a lamp alive
- want backup that stores in a drawer instead of a garage corner
- camp and need a light with three brightness settings plus SOS built in
- charge several devices at once instead of one by one
Skip if you:
- expect it to run a fridge or a space heater. At 88.8Wh a 100W device gets under an hour
- want the solar panel included. It’s sold separately
- need to power a full outage for a whole family, not just small electronics

I Bought It Because the Lights Keep Going Out
Where I live, it rains a lot and the electricity goes off very often. That’s the whole reason this thing is in my house. I didn’t want a generator in the garage. I wanted something that wouldn’t take up much space but that was still powerful, and this MARBERO 88.8Wh portable power station is about the size of a DSLR camera. Just look at the size of it.
It lives in a kitchen drawer between outages, not a garage shelf, not a dedicated corner, a kitchen drawer. The stroller basket works too; it’s 6.12 × 3.69 × 4.19 inches. The orange color sounds like a marketing detail until you’re fumbling for it at 2 a.m. during a blackout and you find it in one grab.
Phone and Baby Monitor, Charging Together
Both charged at the same time, no juggling. I had my phone plugged in and the baby’s monitor plugged in, and the blue light indicated both were pulling power. That’s the part that mattered to me. It doesn’t have to be one by one.
There are six outputs total: two AC outlets rated 150W max, two USB-A, two USB-C. So a laptop can go on one side while the small stuff fills the rest. The on/off is right there on the front, nothing to learn. Okay, simple enough.
It also brings light. Three settings plus the emergency mode, and the listing puts that flashlight at 37 to 68 hours depending on brightness. During an outage that’s the part you reach for before you reach for the outlets.
Keeping It Charged Is the Actual Ownership Cost
Three ways in, and none of them cost you anything after purchase. Wall outlet takes 3 hours to go from 0% to 80%. Car lighter adapter works if you’re already driving to the campsite. And it takes solar, which is where the power station solar setup comes in, except the panel isn’t in the box.
That’s the catch worth knowing. If you’re shopping power station solar panel bundles specifically, this one is listed as “solar panel optional,” so you’re buying a second item to get the solar charging. For my use, outages, I just keep it topped off at the wall and that’s fine. If you’re going off-grid for days, budget for the panel.
No filters, no consumables, no subscription. The battery is rated for over 500 charge cycles with a smart BMS handling overload, over-temperature and short-circuit protection. Rear vents for heat. That’s the whole maintenance story.
88.8Wh Is Small. Know What That Buys.
A 100W device gets under an hour, that’s the ceiling before the battery dies. That’s straight from the listing and it’s the number I’d want someone to read before they click buy, because “power station” makes people picture running a refrigerator overnight. This isn’t that. It’s 24,000mAh, roughly a stack of phone charges plus a monitor plus a light.
For what I asked of it during a storm, that’s plenty. Phone, baby monitor, a lamp, maybe a laptop top-up. Low-wattage things, several at once, for hours. Push past that and the 150W max will stop you before the battery does.
The real comparison isn’t other power stations, it’s whether you want something you can grab off a shelf in the dark versus a gas generator you have to haul out, fuel, and ventilate while your toddler’s monitor dies. At 2.27 lbs, this one wins that specific argument easily. Price moves frequently; check the listing before assuming, it’s been meaningfully below its current level before.
Where It Runs Out
Anything with a heating element is out. Kettles, hair tools, space heaters, microwaves. The 150W surge ceiling isn’t a suggestion. A mini car fridge or a 12V tire inflator works for short periods per the listing, but “short periods” is doing real work in that sentence.
Multi-day off-grid trips are the other stretch. Without the solar panel you’ve got one tank and no refill, and three hours at a wall outlet isn’t an option at a campsite. For a weekend of phones and camp lights, fine. For a week, you need the panel or a bigger unit.
A Year Later I’d Still Keep It in the Drawer
It does exactly the narrow job I bought it for. Rain comes, power goes, and the phone and the baby monitor stay alive without me thinking about it. Heavy duty build, store it anywhere, bright color so it doesn’t disappear, light built in, six ports so nothing waits its turn.
What I’d change: I wish the solar panel came with it. Calling it a solar generator when the panel is a separate purchase is the one thing that bugs me about how it’s sold. The hardware itself I have no complaints about.
A year in, it has survived a drawer, a camping trip, and more power outages than I’ve counted. Phone charged, baby monitor on, light working, every time. If that’s the job you need done, stop looking. Current pricing is on the product page.
Pros
- Charges multiple devices at once. Phone and baby monitor together, no waiting
- Heavy duty but small enough to store anywhere, 2.27 lbs
- Built-in light with three settings plus emergency mode
- Six outputs including two AC outlets and two USB-C
- Bright color so you won’t lose it camping
Cons
- Solar panel isn’t included, despite the solar generator name
- 88.8Wh means a 100W device runs under an hour. Not for appliances
- 150W max rules out anything with a heating element
Frequently Asked Questions
Can it run a CPAP machine overnight?
Only partially. At 88.8Wh you’re looking at a few hours on a low-draw CPAP with humidifier off, not a full night. The listing names CPAP as a use case, but treat it as emergency coverage rather than a nightly solution.
Can I leave it plugged in all the time as standby backup?
The BMS handles over-voltage and over-current protection with automatic shut-off, so it’s built for it. I’d still top it off every few weeks rather than leaving it on the wall permanently, just to cycle the battery. It’s rated for over 500 charge cycles.
What solar panel do I need to buy with it?
Anything putting out DC 13V to 25V at 1.7A max, per the listing spec. That’s the window the input accepts. Buying a panel outside that range is the most common mistake with power station solar charging setups.
Can I take it on a plane?
No. Most airlines cap lithium batteries at 100Wh in carry-on and some require approval above a lower threshold, and 88.8Wh sits close enough to that line that you’d need to check with your specific airline first. For road trips there’s no issue.
Is it safe to use indoors with kids around?
Yes, it’s a sealed lithium battery with no fumes, unlike a gas generator. It has rear cooling vents that need to stay clear and it gets warm under load, so I keep it on a counter rather than the floor where a toddler would grab it.
